本世纪60年代方兴起的眼底荧光造影照相技术更将眼底检查推进到动态的毛细血管水平。但目前在我国广大基层医院,未普及昂贵的眼底荧光照相机,因而眼底病的诊断水平受到限制。为此,作者将滤光片装于直接眼底镜上,试行眼底荧光血管造影观察。材料:苏州医疗器械厂生产的Y2—613型强光源直接眼底镜和提供的激发滤光片与栅滤光片,秒表一个。制作:在直接眼底镜的光路中放置二滤光片,这一点很容易做到。激发滤光片A 直接置于眼底镜照明灯泡前,栅滤光片B 置于眼底镜观察孔前,B 做成活动式(图)
In the 60s of this century, the rise of the fundus fluorescein angiography photography will further advance the fundus examination to the dynamic level of capillaries. However, at present, most grassroots hospitals in our country do not popularize the expensive fundus fluorescence camera, so the diagnosis of fundus diseases is limited. To this end, the author mounted the filter on the direct ophthalmoscope, pilot fundus fluorescein angiography. Material: Y2-613 strong light source direct ophthalmoscope produced by Suzhou Medical Device Factory and one excitation filter and grid filter, one stopwatch. Production: Placing two filters in the direct ophthalmoscope’s light path is easy. Excitation filter A directly placed in front of the fundus lamp bulb, grid filter B placed in front of the fundus observation hole, B made of mobile (Figure)
